Last Updated : 02 Jan, 2025
Java is a general-purpose, object-oriented programming language that was designed by James Gosling at Sun Microsystems in 1991 . The compilation of the Java applications results in the bytecode that can be run on any platform using the Java Virtual Machine. Because of this, Java is also known as a WORA (Write Once, Run Anywhere) language. In modern times, Java is one of the most popular programming languages as it can be used to design customized applications that are light and fast and serve a variety of purposes.

4. Java has an Abundant API
Java has an abundant Application Programming Interface (API) that includes many Java classes, packages, interfaces, etc. This is useful for constructing applications without necessarily knowing their inside implementations. Java has mainly three types of API i.e. Official Java core APIs, Optional official Java APIs, and Unofficial APIs. These APIs overall are used for almost everything including networking, I/O, databases, media, XML parsing, speech synthesis, etc.
5. Java has Multiple Open Source Libraries
Open-source libraries have resources that can be copied, studied, changed, shared, etc. There are multiple open source libraries in Java such as JHipster, Maven, Google Guava, Apache Commons , etc. that can be used to make Java development easier, cheaper and faster.
There are many Integrated development environments (IDEs) in Java that provide various facilities for software development to programmers. Powerful Java IDEs such as Eclipse , NetBeans , IntelliJ IDEA , etc. play a big role in the success of Java. These IDEs provide many facilities such as debugging, syntax highlighting, code completion, language support, automated refactoring, etc. that make coding in Java easier and faster. Java has created a base for the Android operating system and opted around 90% of fortune 500 companies to develop a lot of back-end applications. Also, it plays a great role in Apache Hadoop data processing, Amazon Web Services, Windows Azure , etc.
7. Java is Free of Cost
One of the reasons Java is very popular among individual programmers is that it is available under the Oracle Binary Code License (BCL), free of charge. This means that Java is free for development and test environments, but for commercial purposes, a little pay is required.
Java is platform-independent as the Java source code is converted to byte code by the compiler which can then be executed on any platform using the Java Virtual Machine . Java is also known as a WORA (write once, run anywhere) language because it is platform-independent. Also, the development of most Java applications occurs in a Windows environment while they are run on a UNIX platform because of the platform-independent nature of Java.
9. Java has Great Documentation Support
The documentation support for Java is excellent using Javadoc which is the documentation generator for Java. It uses the Java source code to generate the API documentation in HTML format. So, Javadoc provides a great reference while coding in Java so that understanding the code is quite simple.
10. Java is Versatile
Java is very versatile as it is used for programming applications on the web, mobile, desktop, etc. using different platforms . Also, Java has many features such as dynamic coding, multiple security features, platform-independent characteristics, network-centric designing, etc. that make it quite versatile. It doesn’t matter if you are in high school or are in the first year of your college, if you have the curiosity to learn to code, today is the day to start.
